Contact Closure Over IP

MirX MXNET controllers allow contact closure inputs to control relays in a remote location using a two board design.  Both boards are equipped with one contact closure input and one relay installed.  The contact closure controls the relay on the opposite board.  Boards will find each other on a Local Area Network or over the internet if they are located outside the network.

Contact Closure Input & Output

The relay on the sender board can be used to interrupt the power of a device you are switching and also as a dry contact closure output.  Applications where you need to extend the range of a contact closure over a network with a relay at both locations the MirX will work.  Connect the Contact Closure output of your device to a contact closure input then wire the relay on the opposite board as your contact closure output in a remote location.

Selecting a Wireless Contact Closure Relay

MirC boards boards below have one relay installed and one contact closure input.  You now have your choice of 5, 10, 20 or 30 amp relay installed.  A simple dry contact closure will connect to the input of the sender board and trigger a corresponding relay on the receiver board.  These are sold as a pair and they are paired using the MAC Addresses of the ethernet modules on-board so multiple MirX boards will not interfere with each other.  For more information on selecting the correct relay for your application see Choosing a Proper Amperage.
